As smartphone makers work to maximize screen space on the front of the phone, there is a continual question of what to do with the front-facing camera. Companies like Samsung reserve a large portion of bezel along the top of the device for components like the camera, while more and more smartphone makers have followed Apple's lead and carved a notch out of the top of the screen.

Chinese smartphone maker Vivo is launching a device with another solution: a pop-up camera lens. The camera is hidden most of the time, but open the camera app and the front camera will mechanically rise out of the top edge of the device.
